NonDuplicateRoot

Non-duplicate root

Description

Identify, for each edge, whether it denotes a different partition from the root edge. The first edge of the input tree must be a root edge; this can be accomplished using Preorder().

Usage

NonDuplicateRoot(parent, child, nEdge = length(parent))

Arguments

`parent`	Integer vector corresponding to the first column of the edge matrix of a tree of class `phylo`, i.e. `tree$edge[, 1]`
`child`	Integer vector corresponding to the second column of the edge matrix of a tree of class `phylo`, i.e. `tree$edge[, 2]`.
`nEdge`	(optional) integer specifying the number of edges of a tree of class `phylo`, i.e. `dim(tree$edge)[1]`

Details

This function is deprecated; if you use it, please comment (#32) so that a suitable replacement can be guaranteed.

Value

NonDuplicateRoot() returns a logical vector of length nEdge, specifying TRUE unless an edge identifies the same partition as the root edge.
